N-276
Dodecahedron Loudspeaker

The Nor276 is a high power loudspeaker with omnidirectional characteristics.

• Fulfills the directional characteristic required by the ISO 140-3 standard when mounted on a hard reflecting plane.
• Delivers a continuous sound power level of 120 dB when driven with pink noise at a level of 1 volt RMS over the frequency range 50 to 5,000 Hz. 

Nor258 MLS Synchronizer

Synchronization unit, MLS on Nor840

External syncronization box for use with Nor840 when using the external MLS noise generator Nor257.

The Nor270 is a high power loudspeaker with omnidirectional characteristics. It fulfils the directional characteristisc required by the ISO 140-3 Standard and delivers a continuous sound power level of 120 dB when driven with pink noise over the frequency range 50-6300Hz via the Nor280 power amplifier.

Nor280 Power Amplifier

Our aim is to take the latest technology available to help our customers complete their measurements faster but without loss of precision. With the Nor280 we have again met this objective.This power amplifier is the 4th generation of specially designed units for building acoustic measurements from Norsonic. It is less than half the size and weight, but twice as powerful as its predecessors; it replaces the Nor260 as the preferred amplifier to drive the Norsonic range of full and hemi dodecahedron instrumentation loudspeakers.

• May be operated from the 230-volt AC main supply or from a 12- to 36- volt DC source.
• Output power levels of 200 W continuous (8 ohms), 250 W continuous (4 ohms) or 600 W peak (4 ohms ). 

N-265
Microphone Boom Turntable

Indexing system for acoustical measurements. The indexible boom system allows mast or turntable connection to provide precise (0.01 degree) resolution. Used for building acoustics to get precise spatial variation in sound fields, to use with MLS excitation and analysis instruments, or with a turntable to do precise directional characteristics of loudspeakers and microphones.
